Synergistic compositions of carbamate insecticides

Abstract

Carbamate insecticides are potentiated in their control of insects and mites when used in a composition with trifluoromethanesulfonamides.

What is claimed is: 
     
       1. An insecticidal or miticidal composition of: (1) methomyl; and   (2) 1,1,1-trifluoro-N-(3-phenylpropyl)-methanesulfonamide as potentiator for methomyl; where the weight ratio of potentiator to methomyl is form about 1:1 to 10:1.   
     
     
       2. A method for the control of insects or mites comprising applying to a locus to be protected an insecticidally or miticidally effective amount of a composition of claim 1.
